Not quite Khoand. In T3 this will simply remove the breadcrumbs element. The “You Are Here” bit and the block it is in are coded in this particular template in templates>ja_teline_iii>layouts>blocks>mainnav.php
Simply comment out the bit of code I have highlighted in red below
<div id="ja-mainnav" class="wrap">
<div class="main clearfix">
<?php if (($jamenu = $this->loadMenu())) $jamenu->genMenu ($this->getParam('startlevel',0), $this->getParam('endlevel',-1)); ?>
</div>
</div>
<?php if ($this->hasSubmenu() && ($jamenu = $this->loadMenu())) : ?>
<div id="ja-subnav" class="wrap">
<div class="main clearfix">
<?php $jamenu->genMenu (1); ?>
</div>
</div>
<?php endif;?>
<div class="ja-navhelper wrap">
<div class="main clearfix">
<div class="ja-breadcrums">
<strong><?php echo JText::_('You are here')?></strong> <jdoc:include type="module" name="breadcrumbs" />
</div>
<ul class="no-display">
<li><a href="<?php echo $this->getCurrentURL();?>#ja-content" title="<?php echo JText::_("Skip to content");?>"><?php echo JText::_("Skip to content");?></a></li>
</ul>
</div>
</div>
